Remediation of toxic metals. including Pb and other pollutants has been an
important research subject for environmental studies. In a complete controlled growth
chamber we prepared different Pb treatments and pH values. Four turfgrass species
were used in order to study the potential role of species that may play an important
role for environmental remediation of contaminated soils, and possible mechanisms of
Pb translocation from root to shoot system using kinetic studies. Results revealed that. after 14 days most of Pb accumulated more in root
than shoot. Increasing pH value for one unit particularly at high rate of Pb show that,
mean values of the ratio rooVshoot system reached to almost 12 times. Results also
indicate that increasing Pb concentration, gradually increased Pb content in both (oat
and Shoot. It was noticed that Spartina Patens (D) species, showed higher content of
Pb as compared with other Species. Oata showed that increasing Pb concentration up
to 500 ppm led to increase the dry matter for both Centipede grass and Buffalo grass.
The obtained results also show that rate constant values of ~ were affected by plant
species and part of plants as well. Rate of the translocation of Pb from root to shoot
parts Showed that increasing pH values from 4.5 to 6.5 led to increase the
translocation of Pb from root to shoot. Our results emphasize that turfgrass can accumulate substantial amounts of
Pb and thus could be a major component of such a green liver particularly in urban
and Sub urban regions.
